ABSTRACT
Objective: To evaluate the efficacy of Tuina (Chinese therapeutic massage) at points on abdomen and back meridians in the treatment of infantile colic.Methods: A total of 120 infants with intestinal colic were randomly divided into a control group and an observation group, with 60 cases in each group. In the control group, the parents of the infants were given soothing and health education. In addition to the intervention used in the control group, the observation group was treated with Tuina at points on abdomen and back meridians once a day for 5 consecutive days as a course of treatment. The pain scale score and clinical symptoms of the two groups were recorded before and after treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group, and the difference was statistically significant (P<0.05). The pain scale score of the observation group was lower than that of the control group, and the difference was statistically significant (P<0.05). In the 24 h behavior diary indicators, the daily attack duration, the daily attack times, and the weekly attack days in the observation group were lower than those in the control group, and the differences were statistically significant (P<0.05). Conclusion: Tuina at points on abdomen and back meridians is effective and safe in the treatment of infantile colic.
ABSTRACT
Objective To explore and analyze the clinical characteristics of extremely premature infants at low risk for early-onset sepsis (EOS) , so as to avoid overuse of antibiotics. Method The clinical data of extremely premature infants hospitalized from January 1, 2010 to December 31, 2017 were collected. Extremely premature infants born from mothers without premature rupture of membranes and without maternal clinical manifestations of chorioamnionitis during pregnancy were classified assigned into the low-risk group, and those who did not meet the low-risk conditions were regarded assigned intoas the control group. EOS was diagnosed according to the results of blood culture within 72 hours after birth. The clinical characteristics, treatment and outcome of extremely premature infants between the two groups were retrospectively analyzed. Results A total of 245 extremely preterm infants were enrolled, including 153 (62.4％) in low-risk group. Compared with the control group, mothers in low-risk group had higher rates of gestational diabetes and hypertension, higher rates of antenatal hormone use and lower rates of antenatal antibiotics use; furthermore, neonates in low-risk group had lower rates of Apgar score ＜ 5, higher rates of pulmonary surfactant use, respiratory support and mechanical ventilation, and lower risk of death and incidence of early-onset sepsis. The differences were statistically significant (P＜0.05) . Among In extremely premature infants whose having survival time＞ 24 hours, compared with control group, infants in low-risk group had higher incidences of respiratory distress syndrome, patent ductus arteriosus, intracranial hemorrhage and bronchopulmonary dysplasia, and lower incidence of pulmonary hemorrhage than control group, and the differences were statistically significant (all P＜0.05) . In low-risk group, the risks of death, respiratory distress syndrome, pulmonary hemorrhage and bronchopulmonary hemorrhage in long-term antibiotic group were higher than the short-term antibiotic group. Conclusion Early identification of extremely preterm infants at low risk of early-onset sepsis in extremely preterm infants is of clinical significance in reducing early empirical use of antibiotics therapy.
ABSTRACT
Hypoxic-ischemic encephalopathy (HIE) is the main reason of causing neonatal death and poor prognosis of the nervous system.The treatment of HIE has gone into the era of therapeutic hypothermia,the early,continuous,specification amplitude integrated electroencephalography(aEEG) monitoring for therapeutic hypothermia to screen appropriate cases,assess early the severity of HIE,provide early nerve protection treatment and evaluate the therapeutic efficiency,early intervention and improve the prognosis of the long-term HIE.This paper review the application of aEEG in the therapeutic hypothermia of HIE.
ABSTRACT
Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is an autosomal recessive disease caused by SLC25A13 gene mutations, and is characterized by delayed jaundice clearance, liver dysfunction, and elevated aminoacidemia. The confirmed diagnosis depends on gene analysis. Citrin deficiency is one of the important causes of neonatal intrahepatic cholestasis in China. Recently more and more researches about NICCD were reported. The paper summarized the epidemiology, pathogenesis, clinical characteristics, and progresses in diagnosis and treatment of NICCD.
ABSTRACT
Objective To dynamically observe the effect of compound decotion on changes of Na+-K+-ATPase,Ca2+-ATPase activity,intracellular free Ca2+ contents and CaM expression jn bomogenate and mitochondria of rat brain tissues after traumatic brain injury(TBI)and investigate the molecular mechanism of neuroprotective effect of compound decotion.Methods Rat TBI models were made and divided into sham operation group,TBI group and compound decotion treatment group(treated with comof normal saline,twice per day for seven days.Rats were sacrificed at 24 h,72 h and 1 week after injury to dynamically observe activities of Na+-K+-ATPase and Ca2+-ATPase in bomogenate and mitochondria of rat brain tissues,concentration of free Ca2+ in neurocytes and expression change of CaM in brain tissues.Results The activities of Na+-K+-ATP ageand Ca2+-ATPase in homogenates and mitochondria of brain tissues markedly decreased at different time point and increased gradually after 72 hours in TBI group but wag still lower than that of sham operation group at one week after injury.However,compound decotion could significantly enhance the activities of Na+-K+-ATPageand Ca2+-ATPage(P＜0.05).In TBI group,concentration of free Ca2+ in neurocytes and CaM expression in brain tissues were elevated at different degrees at different time point and reached peak at 24 hours after injury but still lower than that of sham operation group at 72 hours.While concentration of free Ca2+ in neurocytes and CaM expression in brain tissues were significantly lower than those of TBI group at different time point(P＜0.05).Conclusions The neuroprotective effect of compound decotion may be related to its role in increasing activities of Na+-K+-ATPase and Ca2+-ATPase to facilitate cellular metabolism and decreasing concentration of free Ca2+ in neurocytes and CaM expression in brain tissues to mitigate secondary brain injury induced by Ca2+ over load.
ABSTRACT
Aim To investigate the antiepileptic activity of alpha-asarone in three epilepsy models.Methods The MES mice,MST mice and Lithium-pilocarpine rats were divided randomly and respectively into groups each containing 20 animals(?-asarone groups,AED groups and normal control group).Different doses of alpha-asarone were administered to mice/rats in advance in alpha-asarone treated groups,one group received only saline,while the other groups received antiepileptic drug as a reference standard,2 times per day for 28 days.The seizure severity score,seizure latency and total number of animals with seizures were noted to observe whether alpha-asarone had anticonvulsant effect or not in three epilepsy models.Results Alpha-asarone possessed excellent anticonvulsant effect in MES and MST and lithium-pilocarpine models. It significantly decreased the seizure incidence 40%~100% in the MES models and 50%~90% in MST models,and 40%~80% in the Lithium-pilocarpine model. It significantly prolonged the seizure latency 70~180 s in MST mice and 4~15 min in Lithium-pilocarpine rats;It significantly reduced the seizure severity scores 1.96 in Lithium-pilocarpine rats.Conclusions Alpha-asarone had a positive antiepileptic activity.
ABSTRACT
Objective To evaluate whether the pentylenetetrazol(PTZ)model is an appropriate animal model of absence seizure.Methods A series of tests including EEG,active avoidance response(AAR)and passive escape response(PER)in a two-way shuttle box were finished during seizure induced by PTZ(35 mg/kg,ip)in 40 Wistar epileptic rats.Results Epileptiform activity was characterized by bilaterally spike wave discharges synchronously elicited during seizure in PTZ models.During absence seizure induced by PTZ,the latency of active avoidance response was significantly prolonged.AAR positive rate was decreased by 85%.PER positive rate was increased by 56%,and escape failure positive rate was increased by 29%.Conclusion There is epileptiform discharge accompanying transient conscious disturbance during absence seizure induced by pentylenetetrazol.
